I agree it's an interesting debate. If Wright was in this draft I'd be happy to take him 1st OA despite having not played. In general, production makes me feel a lot better about a pick.
I think that's a somewhat difficult question as there's no player precisely like Zetterberg. I do think there are a large number of players that are better than the sum of their parts though: Marchand, Bergeron, Barkov, Stone, Huberdeau, Scheifele, O'Reilly, Pavelski, JVR, Couturier, Saad. Maybe you can take exception to a few names for having size, or hands but I think each of those players is someone who performs better than their tools would imply. Admittedly, like Zetterberg, they're all very responsible, defensively capable players and I don't know if I'm comfortable projecting Eklund to have that defensive impact though I do think he is a good defensive player. Some of these names, Huberdeau for example, had elite skills on draft day and developed into more all arounders in the NHL. There's also players like Point that lacked an elite skill on draft day but developed one later.
I think it's very reasonable to prefer Johnson (just for example) to Eklund because he has more elite tools. But I also think it's reasonable to say that Eklund produced really well, and I'm comfortable projecting him as a second line winger at least. If he develops an elite skill or manages to be an elite all arounder maybe he can even be a 1C. When I feel uncertain about a group of prospects, give me the guy that's producing in a very hard league to produce in.
I also don't think we should ignore that Eklund does have a lot of great tools. Just nothing that stands out as "oh my god what a shot/dangle/pass."
